Stage Tube Lengths

Last updated 10 months ago

The image below shows the equations for calculating the length of each tube. Each of the moving stages are 1/4” longer than the preceding stage, and the first stage is 1” longer than the base tube.

The max tube length for each stage (excluding the output stage) is roughly 40”. The is due to the max safe extension of the CF Springs sold by WCP, which is 40”.
